Pretty strict gun control there. A 3 month waiting period was set up in 2006, followed by needing "special permission" from the government in 2012. They then added that a civilian needs a specific reason for owning one (including hunting, target shooting, or self-defense). In some jurisdictions, actual proof of a genuine need is also required (This might include a documented, current threat to the life of the applicant (self defense), written permission to shoot feral animals on a property where such animals have been declared a pest (hunting), or ongoing, documented membership of a rifle or pistol club (target shooting).)
